Why does int i = 1024 * 1024 * 1024 * 1024 compile without error?
...e behavior is defined unsigned integers (take the mathematical result, add UINT_MAX + 1 as long as the result is negative, subtract UINT_MAX + 1 as long as the result is greater than UINT_MAX).
In the case of Java, if the result of an operation with int values is not in the allowed range, conceptu...
How should I print types like off_t and size_t?
...:
